Consensus-Based Core Set of Outcome Measures for Clinical Motor Rehabilitation After StrokeâA Delphi Study
Introduction: Outcome measures are key to tailor rehabilitation goals to the stroke patient's individual needs and to monitor poststroke recovery. The large number of available outcome measures leads to high variability in clinical use. Currently, an internationally agreed core set of motor outcome measures for clinical application is lacking. Therefore, the goal was to develop such a set to serve as a quality standard in clinical motor rehabilitation poststroke. /
Methods: Outcome measures for the upper and lower extremities, and activities of daily living (ADL)/stroke-specific outcomes were identified and presented to stroke rehabilitation experts in an electronic Delphi study. In round 1, clinical feasibility and relevance of the outcome measures were rated on a 7-point Likert scale. In round 2, those rated at least as ârelevantâ and âfeasibleâ were ranked within the body functions, activities, and participation domains of the International Classification of Functioning, Disability, and Health (ICF). Furthermore, measurement time points poststroke were indicated. In round 3, answers were reviewed in reference to overall results to reach final consensus. /
Results: In total, 119 outcome measures were presented to 33 experts from 18 countries. The recommended core set includes the FuglâMeyer Motor Assessment and Action Research Arm Test for the upper extremity section; the FuglâMeyer Motor Assessment, 10-m Walk Test, Timed-Up-and-Go, and Berg Balance Scale for the lower extremity section; and the National Institutes of Health Stroke Scale, and Barthel Index or Functional Independence Measure for the ADL/stroke-specific section. The Stroke Impact Scale was recommended spanning all ICF domains. Recommended measurement time points are days 2 ± 1 and 7; weeks 2, 4, and 12; 6 months poststroke and every following 6th month. /
Discussion and Conclusion: Agreement was found upon a set of nine outcome measures for application in clinical motor rehabilitation poststroke, with seven measurement time points following the stages of poststroke recovery. This core set was specifically developed for clinical practice and distinguishes itself from initiatives for stroke rehabilitation research. The next challenge is to implement this clinical core set across the full stroke care continuum with the aim to improve the transparency, comparability, and quality of stroke rehabilitation at a regional, national, and international level
The effectiveness of the Liverpool care pathway in improving end of life care for dying cancer patients in hospital. A cluster randomised trial
<p>Abstract</p> <p>Background</p> <p>Most cancer patients still die in hospital, mainly in medical wards. Many studies in different countries have shown the poor quality of end-of-life care delivery in hospitals. The Program "Liverpool Care Pathway for the dying patient" (LCP), developed in the UK to transfer the hospice model of care into hospitals and other care settings, is a complex intervention to improve the quality of end-of-life care. The results from qualitative and quantitative studies suggest that the LCP Program can improve significantly the quality of end-of-life care delivery in hospitals, but no randomised trial has been conducted till now.</p> <p>Methods and design</p> <p>This is a randomized cluster trial, stratified by regions and matched for assessment period. Pairs of eligible medical wards from different hospitals will be randomized to receive the LCP-I Program or no intervention until the end of the trial. The LCP-I Program will be implemented by a Palliative Care Unit.</p> <p>The assessment of the end-points will be performed for all cancer deaths occurred in the six months after the end of the LCP-I implementation in the experimental wards and, in the same period of time, in the matched control wards. The primary end-point is the overall quality of end-of-life care provided on the ward to dying cancer patients and their families, assessed using the Global Scale of the Italian version of the Toolkit <it>"After-death Bereaved Family Member Interview</it>".</p> <p>Discussion</p> <p>This study can be interpreted as a Phase III trial according to the Medical Research Council Framework. In this study, the effectiveness of a fully defined intervention is assessed by comparing the distribution of the endpoints in the experimental and in the control arm.</p> <p>Research ID</p> <p>RFPS-2006-6-341619</p> <p>Trial registration</p> <p>ClinicalTrials.gov Identifier: <a href="http://www.clinicaltrials.gov/ct2/show/NCT01081899">NCT01081899</a></p

Design of the ExCersion-VCI study: The effect of aerobic exercise on cerebral perfusion in patients with vascular cognitive impairment
There is evidence for a beneficial effect of aerobic exercise on cognition, but underlying mechanisms are unclear. In this study, we test the hypothesis that aerobic exercise increases cerebral blood flow (CBF) in patients with vascular cognitive impairment (VCI). This study is a multicenter single-blind randomized controlled trial among 80 patients with VCI. Most important inclusion criteria are a diagnosis of VCI with Mini-Mental State Examination â„22 and Clinical Dementia Rating â€0.5. Participants are randomized into an aerobic exercise group or a control group. The aerobic exercise program aims to improve cardiorespiratory fitness and takes 14 weeks, with a frequency of three times a week. Participants are provided with a bicycle ergometer at home. The control group receives two information meetings. Primary outcome measure is change in CBF. We expect this study to provide insight into the potential mechanism by which aerobic exercise improves hemodynamic status
Balancing the playing field: collaborative gaming for physical training.
BACKGROUND: Multiplayer video games promoting exercise-based rehabilitation may facilitate motor learning, by increasing motivation through social interaction. However, a major design challenge is to enable meaningful inter-subject interaction, whilst allowing for significant skill differences between players. We present a novel motor-training paradigm that allows real-time collaboration and performance enhancement, across a wide range of inter-subject skill mismatches, including disabled vs. able-bodied partnerships. METHODS: A virtual task consisting of a dynamic ball on a beam, is controlled at each end using independent digital force-sensing handgrips. Interaction is mediated through simulated physical coupling and locally-redundant control. Game performance was measured in 16 healthy-healthy and 16 patient-expert dyads, where patients were hemiparetic stroke survivors using their impaired arm. Dual-player was compared to single-player performance, in terms of score, target tracking, stability, effort and smoothness; and questionnaires probing user-experience and engagement. RESULTS: Performance of less-able subjects (as ranked from single-player ability) was enhanced by dual-player mode, by an amount proportionate to the partnership's mismatch. The more abled partners' performances decreased by a similar amount. Such zero-sum interactions were observed for both healthy-healthy and patient-expert interactions. Dual-player was preferred by the majority of players independent of baseline ability and subject group; healthy subjects also felt more challenged, and patients more skilled. CONCLUSION: This is the first demonstration of implicit skill balancing in a truly collaborative virtual training task leading to heightened engagement, across both healthy subjects and stroke patients
Is upper limb virtual reality training more intensive than conventional training for patients in the subacute phase after stroke? An analysis of treatment intensity and content
Predicted risk of harm versus treatment benefit in large randomised controlled trials
Most drugs come with unwanted, and perhaps harmful, side-effects. Depending on
the size of the treatment benefit such harms may be tolerable. In acute stroke,
treatment with aspirin and treatment with alteplase have both proven to be effective
in reducing the odds of death or dependency in follow-up. However, in both cases,
treated patients are subject to a greater risk of haemorrhage â a serious side-effect
which could result in early death or greater dependency. Current treatment licenses
are restricted so as to avoid treating those with certain traits or risk factors associated
with bleeding. It is plausible however that a weighted combination of all these
factors would achieve better discrimination than an informal assessment of each
individual risk factor. This has the potential to help target treatment to those most
likely to benefit and avoid treating those at greater risk from harm. This thesis will
therefore: (i) explore how predictions of harm and benefit are currently made; (ii)
seek to make improvements by adopting more rigorous methodological approaches
in model development; and (iii) investigate how the predicted risk of harm and
treatment benefit could be used to strike an optimal balance.
Statistical prediction is not an exact science. Before clinical utility can be established
it is essential that the performance of any prediction method be assessed at the point
of application. A prediction method must attain certain desirable properties to be of
any use, namely: good discrimination â which quantifies how well the prediction
method can separate events from non-events; and good calibration â which measures
how close the obtained predicted risks match the observed. A comparison of informal
predictions made by clinicians and formal predictions made by clinical prediction
models is presented using a prospective observational study of stroke patients seen at
a single centre hospital in Edinburgh. These results suggest that both prediction
methods achieve similar discrimination. A stratified framework based on predicted
risks obtained from clinical prediction models is considered using data from large
randomised trials. First, with three of the largest aspirin trials it is shown that there is
no evidence to suggest that the benefit of aspirin on reducing six month death or
dependency varies with the predicted risk of benefit or with the predicted risk of
harm. Second, using data from the third International Stroke Trial (IST3) a similar
question is posed of the effect of alteplase and the predicted risk of symptomatic
intracranial haemorrhage. It was found that this relationship corresponded strongly
with the relationship associated with stratifying patients according to their predicted
risk of death or dependency in the absence of treatment: those at the highest
predicted risk from either event stand to experience the largest absolute benefit from
alteplase with no indication of harm amongst those at lower predicted risk. It is
concluded that prediction models for harmful side-effects based on simple clinical
variables measured at baseline in randomised trials appear to offer little use in
targeting treatments. Better separation between harmful events like bleeding and
overall poor outcomes is required. This may be possible through the identification of
novel (bio)markers unique to haemorrhage post treatment
The effects of integrated care: a systematic review of UK and international evidence
BACKGROUND: Healthcare systems around the world have been responding to the demand for better integrated models of service delivery. However, there is a need for further clarity regarding the effects of these new models of integration, and exploration regarding whether models introduced in other care systems may achieve similar outcomes in a UK national health service context. METHODS: The study aimed to carry out a systematic review of the effects of integration or co-ordination between healthcare services, or between health and social care on service delivery outcomes including effectiveness, efficiency and quality of care. Electronic databases including MEDLINE; Embase; PsycINFO; CINAHL; Science and Social Science Citation Indices; and the Cochrane Library were searched for relevant literature published between 2006 to March 2017. Online sources were searched for UK grey literature, and citation searching, and manual reference list screening were also carried out. Quantitative primary studies and systematic reviews, reporting actual or perceived effects on service delivery following the introduction of models of integration or co-ordination, in healthcare or health and social care settings in developed countries were eligible for inclusion. Strength of evidence for each outcome reported was analysed and synthesised using a four point comparative rating system of stronger, weaker, inconsistent or limited evidence. RESULTS: One hundred sixty seven studies were eligible for inclusion. Analysis indicated evidence of perceived improved quality of care, evidence of increased patient satisfaction, and evidence of improved access to care. Evidence was rated as either inconsistent or limited regarding all other outcomes reported, including system-wide impacts on primary care, secondary care, and health care costs. There were limited differences between outcomes reported by UK and international studies, and overall the literature had a limited consideration of effects on service users. CONCLUSIONS: Models of integrated care may enhance patient satisfaction, increase perceived quality of care, and enable access to services, although the evidence for other outcomes including service costs remains unclear. Indications of improved access may have important implications for services struggling to cope with increasing demand. TRIAL REGISTRATION: Prospero registration number: 42016037725
